I have a feeling most of my velocity tweaking will be at home after I record the MIDI in and compare what it should sound like by listening to his recorded DT-10 audio out. My anticipated drummer has never done MIDI recording before, is a great live guy, but non-technical (I can hope he has different velocity maps … I wouldn’t be surprised if he did, as he’s a very solid guy) - AND, I’ve never been an “engineer” outside the confines of the spare bedroom. So though I’m going to go in as prepared as I can be, there will almost certainly be some futzing around no matter what. If I can minimize it by doing things like velocity tweaking after the case … I think that will wind up being best.
